Package : xerces-c
Version : 3.1.1-3+deb7u4
CVE ID : CVE-2016-4463
Debian Bug : 828990
Brandon Perry discovered that xerces-c, a validating XML parser library
for C++, fails to successfully parse a DTD that is deeply nested,
causing a stack overflow. A remote unauthenticated attacker can take
advantage of this flaw to cause a denial of service against applications
using the xerces-c library.
Additionally this update includes an enhancement to enable applications
to fully disable DTD processing through the use of an environment
variable (XERCES_DISABLE_DTD).
For Debian 7 "Wheezy", these problems have been fixed in version
3.1.1-3+deb7u4.
We recommend that you upgrade your xerces-c packages.
